Split / Сплит (2016)

Kevin is a young man who suffers from a split personality. But the whole problem is that not two or even five people get along in it, but more than twenty. He can be anything: a man, a woman and even a child. Once one of his personalities abducts three friends and locks them in the basement deep underground. Frightened girls do not know what to do and why the kidnapper chose them. It is simply impossible to get out of captivity, but soon they notice a woman in the keyhole, who may be able to help them. That's just this stranger himself is Kevin, who says that girls have nothing to fear, and their lives are not threatened. But after a while before them there is one more person of Kevin, a nine-year-old boy, who tells them about a terrible beast, who should soon wake up...
